Homework Statement



What is the wave speed in a brass wire with a radius of 3.35×10-4 m stretched with a tension of 120 N? The density of brass is 8.60×103 kg/m^3.

Homework Equations



v = [tex]\sqrt{\frac{T}{\mu}}[/tex]

The Attempt at a Solution



I have no clue about this problem. It gives me regular density but i need linear density in order for the formula to work and i don't know how or if i even can convert reg density to linear. Nor can i find any other relevant equations that would clear it up for me.

cheers

Hi K3nt70.
Try find the cross-sectional area of the string and see if you can see what to do then.
